Power washing a retaining wall
Hi, I have retaining walls on each side of my driveway. They are made of stone blocks and need cleaned. Do I run any risk of weakening the walls by using the power/pressure washer? Thanks!

Probably not. Are they loosed laid or mortared?
Using a cleaning agent generally makes for quicker work and less need for more pressure.
